I finally got Comcast internet at home. Bought a Linksys Wireless N router. Put a Dynex Wireless G PCI card in my PC at home. On speedtest.net my PC was downloading at about 7500 kb/s In the same chair my MacBook Pro was getting 20,000 kb/s I was using Firefox on both. The Desktop PC is on the floor near my feet and the Mac is on my lap. But the router is in the basement. Can the wireless card in the Mac be THAT much better? Can location make that much of a difference when they're about 2 feet apart?
